The winning numbers were 5, 28, 62, 65, 70 and Mega Ball 5. No details on where the winning ticket was sold were immediately available. But the lucky player overcame miserable odds: The chance of matching all six numbers and winning the top prize is 1 in 302.5 million.

Mega Millions is played in 44 states as well as Washington, D.C., and the U.S. Virgin Islands.

Lottery officials and financial managers encourage people to take time to map out a strategy for investing their hundreds of millions of dollars, and winners must deal with security concerns befitting someone who suddenly is immensely wealthy. Depending on the state, winners have from 180 days to a year to claim their prize.

In eight states — South Carolina, Delaware, Georgia, Kansas, Maryland, North Dakota, Ohio and Texas — winners can remain anonymous, but in the others their identities will become public.

The Mega Millions jackpot grew so large because it had been nearly three months since a player had matched all six numbers and won the top prize. The last time that happened was July 24, when 11 co-workers from California won a $543 million prize.

Although Tuesday’s jackpot was extraordinarily large, it’s no fluke. It reflects a trend toward ever-growing lottery prizes due to changes in the game that worsened the odds with hopes that bigger jackpots would result in better sales.

Officials with the Powerball game were the first to make that move in October 2015 when changing the odds of winning the jackpot from 1 in 175 million to 1 in 292.2 million. Mega Millions followed suit in October 2017, resulting in the odds worsening from 1 in 259 million to 1 in 302.5 million.

While most attention has been on the Mega Millions game, Powerball also has been soaring. The estimated prize for Powerball’s annuity option in Wednesday night’s drawing is $620 million, with a cash prize of $354.3 million.
